upload blocked after a while
 

My problem is that with all gnutella clients after an hour my uploads are blocked.

this is because all the free slots are occupied by users that are next to download but never start.

For example in phex i have all the slots with "initializing" written in status but they never start to download from me but they occupy the slot for ever.

If i cancel their download all returns perfect!

Then again after a variable period i meet clients that block my slots.

it happens also with shareaza.

Am i the only with this problem?

Will i have to manually remove this blocking-my-slots uploads for ever or there is an option to clean them automatically after a certain period?

Thanks in advance.
